Samsung Galaxy J4 (2018)
How long will it last?
Our estimateSupported until May 2021 · Buy-by May 2019
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy J4 (2018) should be supported until around May 2021. Buying it today still gets you about -5.1 years of safe use (Apple's written legal minimum is 5 years).

Frequently asked questions
How long will the Galaxy J4 (2018) get updates?
It is end-of-life. The J4 received a single update to Android 9 and stopped getting patches around 2021.
Is the Galaxy J4 fast enough?
Only for basic use. Its quad-core Exynos 7570 and as little as 2GB RAM make it slow with anything demanding.
Can I still use a Galaxy J4 today?
It handles calls, messaging and light browsing, but the absence of security updates makes it unsafe for sensitive accounts.
